Marks on rear Top of motor box WAS from a Handle Previous owner must have installed. Had "Stainless Straight Blade screws " Self tapping that were cut off flush. Never saw a handle installed like that, just the flush ones, like a another guy mentioned.

But a handle is needed there to aid in lifting box.
Like the ideas of latches on sides.

Still has the same type handle on the lower front, that I see in a lot of photos.
That one was thru bolted. Looks original, with Phillip's head screws.

BOTH were Crappy Zamak !!
Both are being replaced.!!

Teak blocks on sides and front of motor box, still there , and still good, after 40 years...

Thanks for all the replies!!
All my photos come out sideways, all where uploaded in right position ??
